ACETYLEN E-GAS GEN ERATOR.

SPECIFICATION forming part of Letters Patent No. 608,541, dated August 2, 1898.

Application filed March 5, 1898.

ing had therein to the accompanying draW- ings.

The object of my invention is to provide a machine for generating and storing acetylene gas Which will be simple in construction and effective in operation 5 and it consists more especially in an improvement in the means of feeding measured quantities of Water toy the center of the carbid and in such other details of construction as are hereinafter more particularly described and claimed.

In the drawings, Figure l is a perspective vieur of my device. Fig. 2 is a vertical section through the line w of Fig. 4. 'Fig.3is a vertical section through the line y y of Fig. 4. Fig. 4 is a plan view. Fig. 5 is a modiiicationjof the guide in the automatic seating device. Fig. 6 is a detail of a modification of the seating device. Fig. 7 is a detail of the pawl and stops shown in connection with ratchet in Fig. 9. the end of the carbid-holder and meansl of closing the opening therein through Which carbid is introduced. Fig. 9 is a view, partly in section, through the lines cof Fig. 4. Figs. l0 and ll are details of the Water-measuring device.

Like characters of reference indicate the same parts throughout th'e several views.

The tank A is constructed in tWo compartments divided by the septum 20, Whichforms the bottom of the Water tank proper," the: lower portion H being a condensation-chamber. The topof the holder Bis open at 35 for the reception of Weights, which may be used to increase gas-pressure. The pipes 23 and 24, rising from the septum 20, are respectively provided for the inflow of the gas on its Way from the generator C to the gas-holder B and for the outfiour of gas from the gas- Fig. 8 is a detail ofy Serial No. 672,732. (No model.)

holder-B to the service-pipe G, the gas following the direction indicated by the arrows. The pipe 23 terminates at the bottom thereof inthe inflow gas-chamber 32. The pipe 24 terminates at the bottom thereof in the outflow gaschamberl 33. Both these chambers are open at the bottoms thereof for the admission of 'Water supplied to the condensation-chamber H through the funnel 34 (shown in Figs. 2 and 4) for the purpose of sealing, as hereinafter described.

The gas-holder B, open at its bottom, is vertically movable upon the holder-guide 2l, Which rises from the base of the tank and extends through the condensation-chamber and tank to a sufficient height above the tank Vto receive nearly the Whole vertical extent of the gas-holder and passes through a depending tube attached to the holder, which opening is contracted at 22 near the top of the holder and at 22 near the bottom thereof to form close-fitting collars around the holderguide 2l.

The generator O is attached to the side of the tank A, being supported at its outer end by the feet 25. Within the generator C is the carbid-holder 26, constructed in its circumferential Wall of any suitable material having openin gs or meshes through which the hydrated lime may escape from the carbidholder 26 and be deposited by gravity in the generator C below the carbid-holder 26.

The end Walls of the carbid-holder 26 may be constructed of any suitable material. The carbid-holder 26 is held to turn upon the Water-supply pipe 27, extending longitudinally through the carbid-holder 26 in the center thereof. The Water-supply pipe 27 is provided With openings 28 on its under side, whereby Water is) admitted to the center of the mass of carbid in the carbid-holder with' betterresults than if otherwise admitted. The carbid is supplied to the carbid-holder 26 through'ythe opening 29 in the endWall of the generator and a correspondingopening 30 in the end Wall of the carbid-h-older 26,

both of Which openings may be closed by any Well-known mechanicalY means. The `generator O may be relieved of its hydrated lime through the opening 31 in the end of the gen- IOO erator, which may be closed by any welllinown mechanical means. l

For the purpose of automatically rotating the carbid-holder 2G I provide the ratchet 3G, (shown in Figs. 2 and 9,) attached to the carbid-holder 2U and integral therewith. The ratchet is actuated in a step-by-step movement from the holder D through the rod 37, having at its upper extremity, above the tank A, an outward]y-turned end 3S and at its lower extremity, within the tank, an inwardly-turned. end 3U, operating in guides 37', attached to the inner side of the tank A, the link 2 connecting the outwardlyturned end of; the rod 537 to the unweighted end of the lever lr-3, the weighted lever 43 attached between its extremities to a trunnion lo", (shown best in Fig. 7,) the trunnion -l-( having its bearing within the receptacle IG, secured upon the top of the generator C, and pawl pivoted to the free end of the stud 4:4, which is attached lo the lever-trunnion to within the receptacle i6. To prevent the ratchet from back movement, I provide the stops 4:7 -f7, pivoted upon the trunnion Ato within the receptacle lo, so located that one or the other of the stops will constantly engage the teeth of' the ratchet.

lVater is delivered from the tank A to the center of the carbid in the carbid-holder 2b in predetermined charges in the following manner: The stand-pipe 4S opens into the tank A near the septum 2O or at any convenient point for the passage of water, so that it may be raised to a height slightly above the pipe 27 in the center of the carbid-holder, and terminates in a chamber if) of a predetermined capacity. (Shown best in Figs. 3 and 9.)

lVithin the chamber 49 is the float-valve -l-l, having its seats at 5i) and 50'. lVhen the float-valve is seated at 50, water is prevented from flowing from the chamber sti) into the stand-pipe 1S, which is particularly desirable in case of a rupture of the walls of the gasholder I3 or in case of a rupture of the service-pipe G exceeding the capacity of the holder, in which case the holder will drop to its lowest point, carrying the valve til. to its scat 50,' thereby rendering the entire apparatus inoperative until such rupture has been repaired. lVhen seated at 50, water is prevented from flowing into the chamber lf) from the stand-pipe iS. The valve rl-l being guided by the valve-stems 5l and 5l is actuated vertically in a downward direction within thc chamber -110 from the gas-holder Il through the rod 37, heretofore described, the link 3f) resting by its lower end upon the lever l-O, pivoted to the side of the tank A, which in turn rests upon the upper end of the valvestem 5l. The link 3E) is arranged to rest upon lever lO at any desired point within its extent, so that the speed of the valve-float Il in its descent maybe accelerated when so de sired in case but little gas is being consumed. It is plain that the depression of the gasholder 13 by the means heretofore described will downwardly actuate the link 8f) to depress the outer end of the lever 0, whereby the float-valve tl will be forced in the direction of its upper seat 50 in chamber 419 and a quantity of water, which may be predetermined, will pass out of; chamber Lif), through the siphon 52, into the funnel 53, which is integral with the pipe 5t, extending to the carbid-holder 2G, and terminates in perforated pipe 27, through which perforations the water reaches the carbid, as hereinbefore described. It is plain that atmospheric pressure will be exerted upon the water in the pipe 5l by the opening in funnel 53, thereby maintaining the working pressure within the geuerator, as determined by the holder ll, and preventing the escape of from the generator through the water-supply thereto.

Upon gas being generated in the generator C it will pass out from the generator through channel into the inflow-chamber 32 and thence by the course hereinbefore described and indicated by arrows to the service-pipe by way of the gas-holder Il.

The eondensation-chamber II should be supplied with water through the funnel 3i,

prepared for that purpose, up to the point where water escapes from the named chamber through the overflow-pipe F, which is prepared for the overflow of any condensation that may take place during the operation of the apparatus.

For the purpose of preventing possible accidents I supply the following safety devices: From the top of the gas-holder ll, I depend the tube 50, open at its bottom, into which is inserted the blow-off tube l), which communicates with the atmospheric air through the wall surrounding the condensation-chamber II and is also provided with an openingatits bottom into the condensation-cliamber. The walls of the tube 5G do not extend downwardly as far as the outer walls of the gas-holder l, wherefore when the volume of gas inthe gasholder l has raised the gas-holder to its greatest possible height admissible by the stop 57 upon the upper end of the guide-rod 2l the lower end of the tube 56 will be above the water-line in tank A and the gas will pass from the holderll into the escape-pipe l) and then find its way to the atmosphericair. In the event that the gas-holder Il shall become filled with gas to its utmost capacity and the safety device already supplied is not operative from any cause and moisture in the gcnerator C is sufficient to still add to the volume of gas the water from the condensationchamberII within the inflow-chamber32 and outflow-chamber 33 will be forced out of the lower ends of the named chambers and the gas will escape up through the water and through the gas-escape pipe E; but the latter safety device is important only in the event that the safety device previously described should become inoperative by any accident which would prevent the holder from rising IOO to its limit, inwhich case the safety device last described will become operative for the escape of the gas through the named gas-escape pipe. It is plain that the first-named safety device will be operative without increased pressure, while with a slightly-increased pressure the last-described safety device will become operative.

To prevent the return of gas to the generator C and its escape when the generator O is opened for any purpose-as to supply carbid to the carbid-holder 26 or to clear the generator C of hydrated lime-I supply the floating check-valve K, consisting of aninverted cup 58,.supplied with the way 59, which is an annular tube beveled at its lower end, and a guide-rod 60, operating in guides 6l 61'., attachedv to the inner side ofthe pipe 23. When the generator is opened, the float check-valve K will become seated on the top of the pipe 23 and the bottom of the way 59 will enter the water in the tank A and effectually cut-off the return of the flow of the gas in the direction of the open generator. The lower end of the way 59 is beveled to better afford an opportunity for the gas to take up its course toward the gas-holder B on the closing of the generator.

A modification of the iioating check-valve is shown in Fig. A5in which the guide for the' same is a sleeve 62 on the upper end of the tube 23. A further modification of the checkvalve is shown in Fig. 6, wherein a cap 63 is pivoted on the support 64, attached to the side of the tube 23 and having the counterweight 65, an extended portion of the support being bent over the cap 63 to forma stop to define the extent of the valve-opening, which modification is reserved to become the subj ect-matter of a future application for Letters Patentof the United States.
